41.3 General description
The Delta DUPS-1232A UPS converts ac power to dc power to supply the battery.
The battery provides up to 8 h of backup power for the lifeline POTS service,
depending on environmental conditions and load. The UPS also supplies power and
alarm connections to the ONT.
The Delta DUPS-1232A UPS converts ac input power (85 to 264 V ac) to 32 W dc
output power (12.5 to 14.5 V dc) for the battery. The battery is charged and sends the
32 W of power (12.5 to 14.5 V dc) to the ONT. The UPS also provides an auxiliary
power connection that supplies 32 W in the event of a power outage that depletes the
battery backup. The auxiliary power connection supplies power to the ONT but does
not charge the battery.
Alarm outputs are available to monitor the operational status of the battery backup.
The battery backup indicates its status to the service personnel with alarms and to the
ONT by a signal return connection. The ONT can communicate the battery backup
status upstream to the P-OLT.
41.4 Operating modes
There are four operating modes as follows:
• Normal: Under normal operating conditions, the green AC Power LED light is
on. The battery receives power from the UPS and battery charge is maintained.
• Battery power: During a commercial utility outage, the battery power supplies the
load. When operating in battery mode, the ON BATTERY LED light is solid
green.
• Low battery: When the battery charge is more than 45% depleted, the UPS
switches to low-battery mode. In this case, the LOW BATTERY LED flashes
green and the alarm beeps four times every minute.
• Auxiliary power: If the battery backup is depleted, an auxiliary battery can be
connected to the UPS.
41.5 Status LEDs and user controls
Four indicator LEDs and one user control button are present on the front of the UPS.
Each LED is labeled with an icon as well as the user control button as shown in
Figure 41-1. For descriptions of these LEDs and the user control button, see
Tables 41-2 and 41-3.
Note — The battery recharges to at least 80% of full capacity in
18 hours with a normal input.
